Polish Academy of Arts and Sciences within the pauart project commissioned us to design the website providing the online catalogue of the scientific and artistic iconographic collections. Starting from 2014, successive digitization and scientific study has covered graphics and photographs from the PAAS and of the PAS collections. Among them there are Dürer, Breugel and Rembrandt works as well as the extraordinary photographs from the Lanckoronski Phototheca. In the long term the project involves digitization of the whole collection estimated to gather about 240,000 items.
